A study was initiated on poultry farms in order to have an indication of the spread of this new virus in the Netherlands and to investigate whether there is a relationship between its appearance and the currently used vaccine strategy (P. Kühne et al. 2023).
Subclinical Gumboro disease caused by variant strains. What impact do they have?
Classification of Gumboro disease (IBDV) became more complex with the discovery of antigenic variant strains (avIBDV) in America and a highly virulent strain (vvIBDV) identified in Europe. More detailed information on the antigenicity, pathogenicity and molecular structure of new IBDV isolates made it clear that the descriptive nomenclature used for...
Variant IBDV strains from different countries. Are they related to each other?
Infectious bursal disease virus (IBDV) was commonly divided into three main groups according to antigenic and virulence properties: classical virulent (cvIBDV), very virulent (vvIBDV) and antigenic variants (avIBDV).
Gumboro disease in layer hens: Not all vaccines are appropriate
Layer hens are more susceptible than broilers to Gumboro disease virus (IBDV) infection. Therefore, a strict control and prevention plan must be implemented in order to avoid the great economic impact that this disease can cause for layer producers. Clearly, the most important tool for the prevention of IBDV is...
In-ovo co-administration of chicken vaccines against coccidiosis and Gumboro disease in broilers
In-ovo vaccination (IO) in commercial broilers is becoming the preferred method of vaccination in many countries. This is attributable to the advance it represents in the automation of the vaccination process and the obvious benefits that this technology offers in decreased labour costs, especially when large production volumes are managed in broiler hatcheries.
